Vibro-acoustic analysis of a domestic product based on experimental measurement and hybrid modelling
2021
The purpose of this paper is to present a case study whereby a hybrid experimental-numerical model is used to analyse the structureborne
radiation from a domestic product (vacuum cleaner head). The passive (including radiative) properties of the structure
considered are modelled using the Hybrid FE-SEA method. The product’s operational activity, which lies beyond the capabilities
of conventional modelling methods, is characterised experimentally using inverse force identification. The identified forces and
passive model are combined to form a so called Hybrid FE-SEA-eXperimental model
